At this point, why would anyone in their right mind respond to this question and paint a target for all manner of negativity ranging from snark to harassment to malicious action?

> target for all manner of negativity ranging from snark to harassment to malicious action We get get the Borg-esque "resistance is futile" spiel, someone asks for examples. One guy (kinda smugly tbh) points us to his (neat) online course website, claiming that it took him 1 month to rebuild with Claude, ergo GP is right and the non-AI dev is destined to extinction. As WooCommerce didn't end all web development befor…

That is not a coherent reply to my point, which is that you guys are like school yard bullies to people naive enough to throw chum into the water.

We've seen this play out so many times. Nobody working on anything serious is going to volunteer to be a target for your BS.

I sincerely wish that people would stop falling for the "prove you're not hallucinating" trap. If winning was possible - and it's not - there would be no prize but more snark and harassment.

Fable + Ultracode has found a bunch of bugs and issues for me when the workflow agents are doing their exploration. Also the "adversarial" agent seems to surface a lot of interesting stuff. It's definitely proactive, the plan + implementation cycle can take an hour. It has one-shot features I want to add with 100% success. Having said that I wouldn't use it over Opus 4.8 for "smaller" things. With everything cranked…

How did you even afford to use Fable + Ultracode ? I feel like the subscription (even the $200 one) is not enough for this workflow. Are you using API or a company plan?

It was on the $200 sub.

It's like that feeling of power you get from owning a gun that you only bought because you feared all the other people who owned guns.

Comparing freedom of movement to a killing device is beyond any threshold of plausibility. And the whole sentence above is unintelligible here. No, it's really that the ability to move at ease is priceless.

Car crashes kill roughly as many Americans each year as guns.

If you add pollution impacts, cars double the yearly deaths of guns.

My personal experience of Fable 5 doing its own thing has been very positive. I was trying to find the root cause of a crash in a Python module which left no errors in the log or console. Fable wrote a test harness that simulated clicks in the UI, then bisected my code until it found the point where it started crashing. It exaggerated the cause of the crash, then ran a series of bash one-liners to make Python virtual…

There goes my coding assistant (removed by US gov't). It was useful while it lasted. (eye-roll)

Was the fix worth $12 to you?

Curious, which model do you use for Codex? I'm very happy with the solutions '5.5 high' finds. It's like it understands exactly what I mean and it also anticipates all sorts of situations. Before I used '5.5 medium' for some time and it was a bit underwhelming. It may sound funny but it's like it didn't care that much to do a good job.

I use GPT 5.5 High Fast, I often benchmark versus Fable (and previously did versus Opus) and it's night and day. Claude still (and has always) writes far too much code to fulfill a given spec or plan. It misses edge cases and is generally far too verbose. Claude also is (and even more so with Fable) super tokenmaxxing, i.e. it seems tuned to use the max amount of tokens per task, whereas Codex will simply get your jo…

High Fast? I don't see that option in my Codex. I only have 3 models: 5.4-mini, 5.4 and 5.5, each with 4 levels: low, medium, high, extra high.

> friendly Socratic arguing with another engineer who happens to be a robot Ha! Same! Still feels like the best way to go about it, really. I know the dream is to one day remove humans from the loop... but I'll enjoy the dialectic while it still seems the most productive!

Same, I like to call it rubber duck coding (now the duck talks back!) Edit: Now I want an LLM connected rubber duck with a speaker/microphone that sees your screen

Totally doable and I would buy one. Only problem is that most of the time when I'm doing "SWE" stuff I'm around other people and can't have the conversation out loud.

They might also ask why a bunch of static CSS inside a bunch of JavaScript is hiding inside __init__.py[0] - hopefully before trying to fix some detail of the CSS. (I'm surprised to see it actually, since my own use of Claude has mostly yielded well-structured code. But I'm not doing proper vibe-coding, more like friendly Socratic arguing with another engineer who happens to be a robot.) [0] https://github.com/datase…

For my own projects, I'm very happy with an outcome that is "not faster, but better" as a result of my use of generative AI.

I still hope this will be a shared goal in at least some tech companies long-term. But the headwinds are strong. "Not better, but faster" is starting to look like a job requirement.
